WALL FORM OR IEOLD.

Application filed May 28,

To all whomit may concera:

Be it known that I. CHRISTIAN BnYNoLDT, a citizen of the United States,residing at Pittsburgh, in the county of Aliegheny and State ofPennsylvania, have invented certain new and useful Improvements in WallForms or Molds, of which the following is a specification.

This invention relates to wall forms for making concrete walls and thelike, and has particular reference to a buttress wall mold or form. I

' One of the primary objects of .my invention consists in the provisionof an improved wall form of such character that it may be utilized toform buttress walls, such for example as reservoir walls.

Another object of my invention consists in the provision of an improvedwall form, by means of which I am enabled to construct leaning wallswhose tops overhang their bases, or inclined walls.

' provision ofw Still another object of my invention consists'in theprovision of an improved wall form of such character that it may bereadily accommodated to construct walls of different slopes orinclinations or having different tapers.

My invention also contemplates the pro of rigidity, while at the sametime it is adjustable to permit of the attainment of the foregoingobjects. 1 r

In general, my invention is directed to the art may be termed, acollapsiblc wall form.

I accomplish the foregoing, together with suchother objects as mayhereinafter appear, or are incident to my invent-ion, by means of aconstruction which I. have illustrated in preferred form in theaccompanying drawings wherein:

Figure 1 is a transverse section through my improved wall form with theparts in position for the casting of the concrete, the section beingtaken on the line 1.1 of Fig. 2; Figure 2 is an irregular section takenon the line 22 of Figure 1; Figure 3 is a section taken on the line 33of Figure 1 and Figures t, 5 and 6 are sectional views illustratingdetails of my invention.

Referring now to the drawings, it will be seen that in general, theapparatus comprises Specification of Letters Patent.

' a traveler A, adapted to straddle the work,

from the traveler; a rear wall mold section D and adaptedto be carriedby the framowork G, and cooperating withthe section B; buttress wallmold sections orbnlkheads E, also. adapted to befsupported fromthe'framework C and the lower buttress mold sections or bulkheads F. Themoldsections constitute a collapsingyself supporting W ll form which'maybe used with the carrier as a unit to be shiftedto cast the successive.sections of the wall. 01' the traveler may be used with a plurality ofsuch mold forms to carry out what may be termed a telescopic methodofoperation in which the traveler be utilized to set up the forms and toshift'or telescope each form'outside theother forms to anewcastingposition." The invention" will first be described inconnection with the unitary operation ofthe traveler and certain of themold sections. v

The traveler A comprises. a top; section a,

preferably in the shape of a rectangular frame composed of suitablechannels 8 and connecting angles 9; and two side sections and braced bylongitudinal structural members, such as the members-10 and 11. Theupper corners of the side section a?) are braced by the angles 12, andthesidosecor limbs 12, and 0, each side" section being; composed ofapair of truss.es,'suit ably spaced;

tion a is bracedby diagonally disposed rods 1?; (see Fig. j

Theside section b, is preferably secured to the upper section ofthejtraveler, while the side section a is hinged-or pivoted thereto inthe manner. matically at 14; in Fig. 1. The purpose of hinging the sidesection etc the top of the carrier is topermit of adjusting .the angularinclination of the section so that the apparigidly indicateddiagramratus may be utilized in building walls of I differentinclinations or tapers, or in constructing center walls. To this end, Ifurther provide both the top. section and the side section a, at variouspoints, with a .plu-.

rality of holes or apertures 15 adapted-to receive locking pins (notshown) by'means of which the side sect-ion will be supported in anyadjusted position with respect to the top section. At" the corners,Iprovide the side sections with flanged wheels 16 adapted-Q g V V1,413,705

to engage the rails Z, the flanges serving to sufficiently support theside sections against lateral displacement under ordinary conditions ofservice.

The wall mold section B comprises top and bottom rails or beams 17 and18, the vertical angles 19, secured to the rails 17 and 18 in the mannershown in Figum 1, the horizontally disposed wales or nailing strips 20adapted to carry the lagging 21. The mold section is swung or suspendedfrom the top of the traveler by means of jacks 22 and it is supportedfrom the side section 0 by'jacks 23, by which arrangement the wall moldsection is supported adj ustably but securely with reference to the sidesection 0 of the traveler, and in such manner that the mold section maybe adjusted as to its inclination and to the thickness of wall to beconstructed, and may be collapsed from the work after a section of thewall has been cast and has set in order to permit the traveler to beshifted to a new position. In collapsing the mold section toward theside section 0, it will be apparent that the lower end of the moldsection will be cleared from the ground.

Referring now to the swinging frame 0, this frame is composed of uprighttruss members (Z composed of suitable structural members such as anglesor the like, the trusses being spaced and braced by connecting,longitudinally disposed channels 24 and angles 25, or similar structuralmembers. The wall mold section D is composed of lagging 26 suitablysecured to nailing strips carried by the frame C. The frame C isswingingly mounted from the top section of the traveler by means ofjacks 27 which have pivotal connection both with the frame itself andwith the top section of the traveler. The frame U, with its wall moldsection D, is supported and. braced in a manner to be hereinafterdescribed.

As herei'nbefore indicated, the buttress forms or bulkheads,constituting a part of o my apparatus are made in two sections. a-

lower section F and an upper section E. The lower sections F are eachcomprised of longitudinal beams 28; the nailing strips or wales 29; andthe lagging .30. In setting up the lower buttress formsF. the pairs offorms may be connected at their outer ends the detachably mountedspacing and bracing channels 31 (see Figure 1) or other wise braced. Atthe front the pairs of lower buttress forms are preferably spaced apartby the lower wall section G. composed of suitably framings carrying thela gginp; 33.

The upper buttress wall mold sections E each comprise a framework ofstructural members such as the angles 34 and the beams or wales 35 (seeFigures 2 and which carry the lagging 36. A pair. of such buttress wallsections Eare carried by the frame 0 in such manner that the sectionsmay be collapsed toward one another. This is accomplished by supportingthe sections. from the frame C 'by means of pins 37 passing through.slots 38 formed in the longitudinal channels 24: of the frame. 'ihesections are adjusted, i. c. advanced or retracted by means of the jackslocated near the top of the frame C and the jack h) which is secured tothe framework of the mold sections in the manner indicated in Figure 2.

The corners formed by the buttress sections E and the wall section D areclosed by lap joints of the construction illustrated. in i ure 5, frominspection of which will be seen that at the forward edges the but tresssections are provided with beams or strips tl over which are secured thean -2 plates 42 adapted to lap over the lagging 26 of the wall sectionD. The corners formed at the top are also closed by a lap joint ofsimilar construction (see Figure 6). i y the provision of these jointsthe corners of the mold forms are closed so as to properly form thecorners of the wall and buttresses, while atthe same time it will beapparent that they do not interfere with the collapsing of the parts.

The operation of the parts is as follows.

The frame (I) carrying the'wall mold section D and the collapsible upperbuttress mold sections E, is swung to the position indicated in Figure land there supported by such means as the tackle mechanism 45. The wallsection and the lower buttress forms F are now placed in position andproperly braced. after which the frame C is supported and braced bysuitable means, such for example as the horse or truss and the wedges4-6, or the braces 4-4 (see Figure 1) or both: and also by the beam 50.as will appear. The buttress sections E are braced by tightening thewedges 4L7 which are inserted between the upper and lower butt-res.sections the gap between such sections be ing covered over by the plates48 secured to the lagging 35 of the upper buttress sections Figure 4;).v

The other buttress mold sections cooperating with those carried by thetraveler to form the but sees, are nowset in position as indicated bythe dotted lines in Figure 3 and are secured in position by means of tierods 49. or the like. diagrammatically indicated in the drawings. Theends of the but tress sections are preferably closed by end plates such.as shown for example in Figure 5%. The weight from the trusses or ratherfrom the frame C, is transmitted. to the buttress frames or sections bymeans of the beam 50 supported from brackets secured to the frame workof the buttress sections and wedged in position by tlie'wedges 51, asshown in Figure 2. V

' The section of the wall is new cast and after the concrete has set,the tie rods 49 are first removed, which permits of the removal of thelower sections F of the buttress form, after which it is possible tocollapse the buttress sections E, free of the concrete, by means of theturn buckles 39 and the jack Frame C and together with. it, the wallsection D and the buttress sections E may now be shifted or swungrearward to the dotted line position of Figure 1, by'means of tacklemechanism shown, or by other suitable mechanism, and the wall section Bmay be retracted in the'manner previously described, by means of thejacks 23. The traveler may now be'shifte'd to a new position and theparts positioned for another casting operation.

It will be seen from, the foregoingthat I have provided a simpleapparatus whereby I am enabled to cast a sloping wall, such as'aresuitab e for reservoirs,dams and the like; and that the apparatus may bereadily adapted to build walls of different inclinations and tapers. Itwill also be apparent that the form may be utilized in casting centerwalls by the substitution of the proper form of wall sections, in whichconnection it is to be observed that the mold sections shown may bereadily detached and others substituted therefor where necessary.Furthermore, the collapsing of the parts can be readily accomplished,and all of the parts when assembled constitute a rigid form. lVithregard to the collapsing of the mold form, it will be observed that theside section I) of thetraveler while it its open to permit of theretraction of the frame C and the buttress sections E, is neverthelesssufiiciently rigid. because of the truss construction employed which isof considerable width at the top.. (See particularly Figure 1.)

Referring now to the telescopic method of operation, i. e. the useofthetraveler with a plurality of mold forms, the apparatus is employedas follows 1 v The traveler A is used as a carrying memher to set up theforms, for the forms, as

will appear, are self-supporting when set up and it will be obvious thatthe tackle mechanism and thejacks 22, 23 and 27 can be readily detachedfrom the mold section to which they are respectively attached at oneend, as a result of which the traveler may be utilized to set up anydesired number of wall forms. 1 r

7 It will be apparent that the mold sections D,.E, F and G, are selfsupportingwhen'set up in the manner previously described, and

the mold section B may be readily supported from the other sections byany preferred means and detachably secured in po-- sition by connectingelements, such for example as the tie-rods 60, which may be removedpreparatory to collapsing the form. When it is desired to shift any ofthe mold forms, the traveler is. brought into position and properlycoupled to the mold section,

shapes difl ering from the buttresses shown. I The term buttress,therefore, is employed. in the specification and claims -hereof 1n abroad sense.
